a couple of thinkpad x230 + ubuntu tweaks

- zshrc for the hostname color
- yet another location for photocp to check when looking for pics

So yeah, for some reason I'm running Ubuntu again for a minute.  I swore
off this distro when it first really went off the rails, UI wise (not to
mention broken-ass-drivers wise), but I wanted a newish kernel and I'm
too busy to sit around reading about config options and recompiling for
a solid day to get all the stuff on this laptop working.

[ Setting:

  It's a beautiful fall day outside.  You can hear a lot of construction
  going on in Lyons.  I'm sort of cleaning the place up after having been
  absent for a couple of months.  I went to Winfield right after the
  flood, lived at Todd's and at SparkFun and in this trailer in Hygiene
  after that.  This is the first I've been home, like in the sense of
  actually _being in my house_, since some time around the 11th.  I didn't
  realize how much I missed it until now. ]
